A new method for construction of complex pseudorandom phase sequence diffusers for diffraction-limited holography is presented. The irradiance fluctuation in the reconstructed image can be suppressed by modifying the size of the sampling area associated with the specific phase terms. The advantage of this diffuser is discussed in terms of the power spectrum and the signal to noise ratio.
